The current kernel driver does not consider I2C_IPGCLK_SEL (424 bit

For NXP ls1046a SoC, the i2c clock needs to be configured with the
appropriate bit of RCW, so we add the guts node (GUTS/DCFG global

NXP Layerscape SoC have up to three MUL options available for all

The current kernel driver supports MUL=1 by default ,but doesn't have
the IBC and SCL Divider entries in vf610_i2c_clk_div
According to LS1046A Reference Manual, for the i2c controller, you have
up to three MUL options available for all divider values. Therefore, we
need to determine which MUL to use in the device tree for driver use.
The "mul-value" property provides which mul is used in our driver.

Well, apparently there's some odd libc issue accoprding to Florian, so
there *might* be something to it.

The comment for ntb_dev_ops and ntb_dev incorrectly referred to
ntb_ctx_ops and ntb_device.

Fix below fall through build warning:
drivers/clk/imx/clk-pllv3.c:453:21: warning:
this statement may fall through [-Wimplicit-fallthrough=]
pll->denom_offset = PLL_IMX7_DENOM_OFFSET;

Hi, Stephen
Thanks for notice.
As it is intentional, I will send out a patch to add "/* fall through
*/" to avoid this build warning,
Anson.

Hi Lukasz,
I have no objection about this patch.
Instead, as I commented on v4, in order to reduce the confusion
about multiple clock definitions with same bit range of DIV_CDREX0,
You need to add the additional comment and you better to
define the three clocks at the nearby in this driver.

Use __maybe_unused for power management related functions
instead of #if CONFIG_PM_SLEEP to simply the code.

Changes since V1:
- use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() to make sure snvs_rtc_pm_ops is
empty when PM is off.
---
and catch some things that GCC can't.
All of these warnings have now been fixed in -next across arm, arm64,
and x86_64 defconfig/allyesconfig so this should be enabled for everyone
to prevent more from easily creeping in.
As of next-20190429:
$ git log --oneline --grep="sometimes-uninitialized&
The pllv4 supports fractional-N function, the formula is:
PLL output freq = input * (mult + num/denom),
This patch adds fractional-N function support, including
clock round rate, calculate rate and set rate, with this
patch, the clock rate of APLL in clock tree is more accurate
than before:
